A high-yi Organic m PCB Substrate yawanci ya ƙunshi duka nau’in dielectric (epoxy resin, fiber gilashi) da kuma jagora mai tsabta mai tsabta (rufin jan karfe). Mun kimanta da dacewa sigogi na buga kewaye hukumar substrate ingancin, yafi ciki har da gilashin mika mulki zazzabi Tg, thermal fadada coefficient CTE, thermal bazuwar lokaci da bazuwar zazzabi Td na substrate, lantarki Properties, PCB ruwa sha, electromigration CAF, da dai sauransu.

Kullum, substrate kayan for buga allon za a iya raba biyu Categories: m substrate kayan da m substrate kayan. Gabaɗaya, mahimman nau’ikan kayan ƙwaƙƙwaran ƙaƙƙarfan kayan abu shine laminate na jan karfe.

Dangane da kayan ƙarfafa hukumar PCB, gabaɗaya an raba shi zuwa nau’ikan masu zuwa:

1. Phenolic PCB takarda substrate

Domin irin wannan allo na PCB yana kunshe ne da almarar takarda, katako, da dai sauransu, wani lokaci yakan zama kwali, allon V0, allon kare wuta da 94HB, da dai sauransu. Babban kayansa shine takarda fiber na itace, wanda shine nau’in PCB. hada da phenolic guduro matsa lamba. farantin karfe.

Siffofin: Ba mai hana wuta ba, ana iya naushi, ƙarancin farashi, ƙarancin farashi, ƙarancin ƙarancin dangi.

2. Composite PCB substrate

Irin wannan katakon foda kuma ana kiransa foda, tare da takarda fiber fiber takarda ko auduga fiber fiber takarda azaman kayan ƙarfafawa, da gilashin fiber gilashi azaman kayan ƙarfafa saman a lokaci guda. Abubuwan biyu an yi su ne da resin epoxy mai hana harshen wuta.

Akwai fiber gilashin rabin gilashin guda ɗaya mai gefe guda 22F, CEM-1 da allon gilashin rabin gilashin CEM-3, daga cikinsu CEM-1 da CEM-3 sune mafi yawan abubuwan haɗin ginin ƙarfe na ƙarfe.

3. Gilashin fiber PCB substrate

Wani lokaci shi ma ya zama epoxy jirgin, gilashin fiber jirgin, FR4, fiber jirgin, da dai sauransu Yana amfani da epoxy guduro a matsayin m da gilashin fiber zane a matsayin ƙarfafa abu.

Siffofin: Yanayin aiki yana da girma, kuma yanayin ba ya shafar shi. Ana yawan amfani da irin wannan allon a cikin PCBs masu gefe biyu.

4. Sauran substrates

Baya ga abubuwan da ake yawan gani a sama guda uku, akwai kuma na’urorin ƙarfe da kuma allunan da aka gina da yawa (BUM).

Fasahar kayan masarufi da samarwa sun wuce rabin karni na ci gaba, kuma abin da ake fitarwa a duniya a shekara ya kai murabba’in murabba’in miliyan 290. Wannan ci gaban ya samo asali ne ta hanyar ƙirƙira da haɓaka samfuran lantarki, fasahar masana’anta na semiconductor, fasahar hawan lantarki, da fasahar hukumar da’ira ta buga. Kore.
